ENERGY MANAGEMENT IN THERMAL POWER PLANT

INTRODUCTION
Thermal Power Plants are the most important source of power generation. They are based on the Rankine Cycle where high pressure and high temperature steam raised in a boiler is expanded through a steam turbine that drives an electric generator. In a thermal power plant, the chemical energy stored in fossil fuels such as coal, fuel oil, natural gas is converted successively into thermal energy, mechanical energy and finally electrical energy for continuous use and distribution across a wide geographic area. Thermal Power plants have very high availability. Their unplanned or forced outage rates are very low. Thermal Power Plant assets need to be flexible to meet rapidly fluctuating demand levels. They also need to remain reliable and demonstrate that every effort has been made to minimize environmental impacts and maximize efficiency. LITERATURE REVIEW

Energy Management has become very important nowadays. It is the control of energy consuming devices for the purpose of minimizing energy demand and consumption. Business, industry and government organizations are all been under tremendous economic and environmental pressures. Being economically competitive in the global marketplace and meeting increasing environmental standards to reduce air and water pollution have been the major driving factors in most of the recent operational cost and capital cost investment decisions. Energy Management hence, has been an important tool to help organizations meet these critical objectives for their short term survival and long-term success. Energy management helps improve environmental quality. It reduces the load on power plants as fewer kilowatt hours of electricity are needed. Hence, less thermal pollution at power plants and less cooling water discharge are produced. Reduced cooling requirements or more efficient satisfaction of those needs means less CFC usage and reduced ozone depletion in the stratosphere....
